3. Routing protocols in Wireless Mash Networks
Ad hoc On-Demand Distance Vector (AODV)
Optimized Link State Routing Protocol (OLSR)
Nodes advertise information only about links with neighbors.

4. Motivation
There are many traditional routing protocols in WMS, but they are not flexible enough for some requirement such as load-balancing.

5. System architecture
Architecture of an OpenFlow Mesh Node

6. System architecture
Architecture of the core network

7. Evaluation-Forwarding performance

8. Total control traffic caused by OLSR and OpenFlow

9. Evaluation -seamless handover

13. TCP throughput from the core-network to the station during two handovers (after 15 and 30 sec.)

14. Conclusion
The architecture combines the benefits of OpenFlow (flexible packet forwarding) and WMNs (self-configuration and error-resilience)
Handover with OpenFlow can provide a more efficient way for access point choosing.
